The improvement of the safety performance of the cable mainly depends on a number of factors, including the choice of insulation materials, the protective effect of the sheath, and the design of the cable structure. Here is a detailed explanation of these aspects:

1. Selection of insulation materials: Insulation materials play a vital role in cables, which can prevent current leakage and electrical short circuit, thereby protecting the safety of users and equipment. The insulating material shall have good electrical properties, heat resistance, pressure resistance and environmental protection performance. By using insulation materials with good heat resistance and strong voltage resistance, the high temperature resistance and voltage shock resistance of the cable can be effectively improved, and the risk of cable failure in high temperature or high voltage environments can be reduced.

2. The protective effect of the sheath: the cable sheath is a protective layer covered outside the cable insulation layer, which can protect the insulation layer from mechanical damage, chemical corrosion and environmental factors. Sheath materials usually have good wear resistance, tensile strength, impact resistance and weather resistance. By choosing good quality sheath material and adopting reasonable sheath structure design, the mechanical strength and protection ability of the cable can be effectively improved, and the service life of the cable can be extended.

3. Design of cable structure: The structural design of cable also has an important impact on its safety performance. Reasonable cable structure should take into account the conductor, insulation layer, shielding layer, sheath layer and other parts of the reasonable cooperation and interaction. For example, in the selection of conductor cross section, the appropriate conductor cross section should be determined according to the current transmission needs to ensure that the cable will not cause safety accidents due to conductor overheating during transmission. At the same time, the design of the shield layer can effectively reduce the electromagnetic interference and signal transmission error, and improve the transmission efficiency of the cable.

To sum up, the safety performance of the cable can be effectively improved by selecting high-quality insulation materials and sheath materials, adopting reasonable cable structure design and strictly controlling the manufacturing process and quality inspection of the cable. These measures can reduce the risk of cable failure during use, ensure the stable operation of the power system and the safety of users.
